Application filed July 12, 1830. (No model.)

To all whom it may concern.-

Be it known that -I, REUBEN M. ROSE, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Attachments for Sewing-Machines for Embroiderin g, Fancy Stitching, and

`Darning Purposes, of which the following is aspecification.

My invention relates to spring-pressure attachments adapted to admit of their being easily attached to and detached from the presser-bark or other-portion of a sewing-machine, andorganized to be raised or relieved bythe action of the needle-carrier from pressure on the material as the needle is withdrawn from the latter, and so as ,to permit the movement of the cloth or material by hand in various directions and to any desired distance, as the varying nature of the Work to be done may require.

,Such attachments have been made compris- `inga base-piece or socket adapted to be attached to the presser-bar or other part of the machine, and a rod or piece iitted in guides in said base-piece or socket, having a foot at the lower end for pressing downward upon the `material, and an arm near the upper end,

through which the rod or piece is raised from the material when it `is desired to shift the latter.

The `object of my invention is tosimplify the construction of such attachments by reducing the number of parts of which they are composed, and also to afford-the movable part of such attachment a strong and 'adequate support.

To this end my invention consists in novel j combination of parts, which is fully illustrated in the accompanying drawings, in which- Figure 1 represents a side view of a portion of a needle-bar and presser-bar having my improved attachment securedVl thereto. Fig. 2

represents a transverse section of the presserbar and a plan of the attachment. Fig. 3 represents a'face view of the attachment. Fig. 4 represents a perspective view ofthe base-plate or stock-piece, and Fig. 5 represents a perspective view of the piece or'plate adapted to slide or move in the ways or gibs of said baseplate or stock-piece.

' Similar letters of reference designate corresponding parts in all the figures.

A designates the presser-bar, to which, in this example of my invention, the attachment is secured, and B designates the needle-bar, carrying the needle a.

C designates the base-plate or stock-piece of my attachment, to belsecured to the presser-bar A, and here represented as having an angle-plate or angular projection, b, secured to its back by riveting, fitting the presser-bar, as shown clearly in Fig. 2, and adapted to be secured by a screw, c.

In lieu of the form of projection here shown, the attachment may be provided with one to fit the side of any presser-bar, or to lit in a slot in the end of the bar, or to be secured to `the bar or to any part of the machine in any way.

The side edges of the base-plate or stockpiece C are bent up or turned over, so as toform gibs or ways d, as shown clearly in Figs. 2 and 4, and a tongue at the top is provided with a hole, e, and bent over so as to form a guide, the use of which will be explained hereinaften a tongue, bent outward at the bottom to form a presser-foot, j', which is perforated to permit the passage of the needle through it. At the upper end the plate D is furnished with a tongue, which is inserted through the guide c ,and bent outwardly, so as to form an arm, for a projection, h, on the needle-bar B to strike against on its upward movement to raise the presser-footy and release the material being operated on.

As represented clearly in Fig. 2, the arm g projects at a right angle to the plate D, while the footf is bent to one side, so that when the attachment is set to allow the needle a to pass through the perforation in the foot f the arm g will project on one side of the needle-bar. The arm g may be bent in any direction, to adapt the attachment for use upon machines in which the needle-bar is variously arranged relatively to the presser-bar.

Around the tongue'forming the armg, beloW the guide c, is a coiled spring, t', which eX- erts a constant downward pressure upon the presser-foot f, and the plate D has in it two slots, j, (see Fig. 5,) at the sides ofthe ton gue which forms the arni g, into which the spring 'i ts, whereby 1 ain enabled to get a long springe,` and still retain long bearings for the plate D in the gibs or ways d.

It will be readily understood that the baseplate or stock-piece, with the gibs or ways (I, furnishes a broad bearing for the plate D, and thus affords adequate support to the latter, and that a simple and desirable attachment is produced, inasmuch as only three parts, exclusive ofthe spring, are required in its construction.

Whatl claim as my invention, and desireto secure by Letters Patent, isi 5 The combination of the base-plate or stockpiece C, having the fastening-projection b, gibs or ways d, and guide e, the movable plate D, fitted loosely in said gibs or ways, and provided with the presser f at its lower end, and zo the arm g projecting from its upper end, and a spring arranged to force said movable plate downward, substantially as described.
